Shad,
While doing the major on my Lycoming O-235 I disassembled the MA-3 carburetor
and put the black composite float and the rubber tipped needle in gas. I tested
to be sure it had ethanol. They were submerged in a sealed quart jar for about
9 months with no degrading. So I will not get heartburn over putting some ethanol
laced gas in my Piet.
Also for you guys building, ACS and MAC's Antique Auto Parts has a float unaffected
by ethanol. I bought mine from Mac's.

| Subject: | Stromberg Notes. |
Crew, if I may...
I just received last night a bunch of papers from Doc M. (BPA newsletter) a
bout Stromberg carbs.- There is some GREAT intell. in these papers.
Anyhoo, from what I remember, (I read through them once kinda fast)- orig
inal Strombergs used SS needles and sharp cornered, (the sealing edge, if y
ou will) brass seat.- Later came the noeprene tip SS needles that used a
rounded cornered seat. This combination at the time was the fix all to carb
. leaks. Having seen this, other companies jumped on the band wagon. These
copied needles were sub standard with machining, finish and type of tip use
d. Once the FAA approved auto fuel and the fuel found it's way into these c
arbs. the neoprene tipped needles started to fail, as described in another
post, by swelling.- The original, high quality neoprene tipped needles wo
rk fine with aircraft fuel only, but are getting harder to find and disting
uish from the "copies."- The rounded seat required for this needle accord
ing to what I read, is almost impossible to find.- Even so, these good ne
edles are very old and most have hardened and are brittle.
The solution next was the Delrin needle, which is impervious to both fuels
and their additives, if any.- This needle uses the sharp cornered seat li
ke the SS needles.- Problem now is this needle is light weight and a weig
ht needs to be added to the float arm to help seat the needle. I believe if
this mod is done, the carb. must be marked with a 1" dia. yellow dot. I am
sure someone here can reference this mod and post it.- Also, with this n
eedle being relatively soft, lapping the needled has proved difficult and s
ome have ruined them all together trying.
Most have kept, or have gone back to the SS needle and sharp cornered seat
as it can be used with any fuel and requires no mods to the float.- (I be
lieve this SS needle/brass seat combo. is what is readily available still.)
As Ryan mentioned in a previous post, lapping helps mate the sealing surfa
ces.
I have a NAS3B Stromberg as opposed to the NAS31A (I believe). I was surpri
sed to learn that there is a wide variety of these carbs. specifically asse
mbled with needles, jets, bleed holes, etc. for specific engines and fuel d
elivery systems. (gravity or pressure)- There are also mods made if these
are used in a tail dragger type planes. (They were not designed for tail d
raggers.)- I was also happy to find out from checking the numbers on my c
arb. that it is correct for my A-65. It currently has the original, not cop
ied, neoprene tipped needle and round cornered seat. It appears to be like
new, however, not knowing what types of fuels may or may not be readily ava
ilable, I plan to switch to the SS.
You can be assured I will be re-reading these documents over a few times an
d digging out the other intell. I have for the various mods, tips, tricks a
nd procedures.- I am curious to see how all this information compares and
how to apply it to my carb. rebuild...which I may start soon.
As I said, the above is what I remember reading from the very valuable docu
ments I received from Doc. He received them from yet another, whom I can't
remember his name.- Thanks to both of them for providing this information

An additional comment about lapping - an easy way to lap a needle valve seat
is to chuck the needle in your drillpress with the speed set as slow as it
can go. Smear some Crest toothpaste (the original type) on the valve seat
and with the needle turning slowly, use the drill press to push the needle
into the valve seat (hold the seat so it can't spin). The toothpaste has
enough abrasive in it to do a nice job of lapping the seat to get a good
seal with the needle.
That's how I did it when I overhauled my Stromberg and it has worked well.

Michael,
I'm not sure what document you are talking about, but I'd
guess there is a copy of it in my "archive" of all things small
Continental. Check the link below. I apologize for the sloppy
organization, I intend to improve that when I retire in 32 years:

One of these documents
probably has the information you are referring to. You may need to copy

My humble experience with fuel.
Lots of No Ethanol Auto fuel in Oklahoma.
Not any Ethanol Free Autofuel in Texas. Even for Boats or 4 wheelers. I have not
found any. Even in small towns. I have done several internet searches and have
never seen it in person.
Metroplexes with smog problems require Ethanol gas. I guess in Texas they dominate
the market so much that you can't get it otherwise. In NW Oklahoma most of
the Gas stations have signs that say "NO ETHANOL"or "Alcohol Free gas!"
We fly Mid grade or premium Autofuel in my buddies 1947 Aeronca Champ (A-65) and
in my 1948 Beech Bonanza (E-185-11). Though in Texas I use AVGAS in my Vtail.
The regular unleaded octane is 86 or 87 Octane. Both STCs call for 87 Octane.
I have noticed small problems when using the 87 Octane that disappear when I
use 89 or higher in my Bonanza.
OT For my Bonanza, I keep my right tank full of 100LL and run Autofuel in the other
tanks. Upon landing I run 100LL until I think it is all the way from the
tank and the Pressure Carb is full of it. 100LL is better for the rubber gaskets
in my Carb. Unleaded car fuel hardens these Expensive rubber parts. 100LL
is much more stable for storage. The Current Auto fuel formulas seem to turn to
varnish much faster than they did even 10 years ago. For long term storage,
I have had good success putting STABIL in my Old Suburbans when I have put them
in storage for months and even years.
Blue Skies,
Steve D

Not sure how up-to-date this information is, but it appears that there are some
locations in TX that sell ethanol-free gas;
